If your man seems to devour the spiciest dish every time you grab Mexican, science may have a weird insight into how his heated taste preferences might be affecting his heat between the sheets.

According to a study from researchers at the University of Grenoble, researchers handed 114 men aged 18 to 44 a plate of mashed potatoes and a bottle of chili sauce. They were simply told to add the hot sauce to taste. This amount was then measured, along with the guys’ testosterone levels.

Interestingly, the men who added the most hot sauce also had the highest level of the hormone, which is linked to just about every trait in the Alpha Male Handbook: adventure-seeking, gambling, high-energy social groups and, of course... high sex drive.

"These results are in line with a lot of research showing a link between testosterone and financial, sexual and behavioural risk-taking,” says study author Laurent Begue, according to The Telegraph. "In this case, it applies to risk-taking in taste.”

That said, the researchers aren’t entirely sure whether testosterone drives spicy food consumption or vice versa, in a total ‘Which came first, the chicken or the egg?’ situation. “It is also possible that the regular consumption of spicy food contributes to increasing testosterone levels,” says Begue, “although so far this has only been demonstrated on rodents."

Either way, it's valuable insight to keep on file. If you’re on a date with a new dude and you're noticing food hot, there’s a good chance he’ll keep it hot in the bedroom, too.
